Title: Improvements in shifting register circuits and the like
Inventor: CLAPPER GENUNG LELAND
IPC: G11C19/20
Filed: 1955-02-11
Abstract: 764,802. Pattern-movement stepping registers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 11, 1955, No. 4128/55. Class 106 (1). ). In a shifting register comprising a; plurality of hard valve triggers adjacent stages are coupled by normally conducting hard triodes. Negative shift pulses on a line 22, Fig. 1, applied to the left-hand grid of each trigger turn each trigger " off (right-hand side conducting)- if it was not already "off"-and any trigger that was " on " in going " off momentarily cuts off the coupling triode V3 which applies a positive pulse to the right-hand grid of the next higher stage. The leading positive going edge of this pulse, occurring substantially simultaneously with a shift pulse, merely tends to accentuate the effect of the shift pulse, on the next higher stage, but the negative going trailing edge causes the next higher stage to go " on " a predetermined time after the arrival of the shift pulse. Thus registered data is positively shifted. In a modification each stage has an additional output triode to enable registered data to be dynamicised in either serial or parallel form.

Pencil-holder.-In pencil holders of the screw-propelling type, the follower c is provided with an uninterrupted thread engaging an internally threaded portion b of the casing a, and travels longitudinally upon a partly slotted lead tube d. when the latter is rotated, the lead being projected by a follower wire e located within the lead tube and connected to the follower by a right-angled bend projecting through the slot. A portion e<1> of the wire follower is also offset to engage the edges of the slot. The lead tube d is secured at its upper end to a tubular member f which forms a chamber for spare leads and is closed bv a screwed end cap h which serves also as a means for rotating the lead tube, follower, and follower wire. The lower end of the lead tube is split to form two or more jaws and is shaped conically to correspond with the lower end of the casing, the engagement of these conical surfaces providing a firm grip upon the end of the lead when projected for writing. A plunger j normally held against the lower end of the screw-threads b by a spring j is depressed if the end cap h is further rotated after the whole of the lead has been projected, the follower then leaving the threads and rotating idly in the space beneath. On rotating the end cap in the opposite direction the follower again engages the threads b. The spring j<1> is supported by a disc j<2> secured beneath it, and a tubular projection on the underside of the disc carries a. conical sleeve k which guides the lead tube passing through it. Pads i<1> provided at the upper and lower ends of the refill chamber relieve the jar upon the leads while being carried, and by saturating the pads with a suitable substance such as a spirit or spiritous compound the leads are preserved from hardening.

Abstract: 452,564. Pile drivers. BURGESS, A. F., 10, New Court, Lincoln's Inn, London.- (Menck & Hambrock Ges. ; 78, Grosse Brunnenstrasse, Hamburg, Germany) Feb. 14, 1936, No. 4511. [Class 68 (ii)] [See also Group XXII] In an internal - combustion pile driver of the kind comprising a cylinder and piston which separate after the explosion, the parts are arranged so that the anvil and the piston are out of contact with each other for a short time after the delivery of each blow. The Figure shows a pile driver in which the monkey is a cylinder 1 separated from a piston 2 and movable on guide rods 3 attached to cross-heads 4 slidable upon a vertical stanchion forming part of the pile-driver frame. The anvil 8 capping the pile 10 is also slidable upon the vertical stanchion. The monkey cylinder 1 has two impact surfaces 7, each about a quarter of the circle, one of which passes through the part 4 as it descends. As it strikes the anvil 8, the piston 2 remains momentarily stationary, and separates from the anvil as it moves down ; then the cylinder reaches the piston, and the gases in the cylinder drive the piston down again until it bears on the anvil. In a modification the cylinder 1 is on the anvil, and the piston serves as a monkey. In another form, the parts 7 are omitted, and the monkey cylinder falls on the rim of a cap-shaped anvil fitted in a saucer-like anvil plate on the top of the pile 10. The contact surface between the cup and saucer is spherical to enable piles to be driven when they are aslant.

Title: Improvements in polymeric materials and in processes for their production
IPC: C08G73/08
Filed: 1946-02-13
Abstract: Linear polymers containing the 1 : 2 : 4-triazole nucleus, which may be obtained as described in Specifications 612,609 and 613,020, are reacted with a bifunctional substance containing two amide-forming groups, of which at least one will react with a terminal group of the polymer to form an amide group, the reaction being carried out with the reactants in a mobile state and being stopped while the polymer is still linear.  Suitable polymers range from dimers of the formula HOOC.R1.T.R11.COOH, where T is a 1 : 2 : 4-triazole nucleus, and R1 and R11 are divalent organic (preferably hydrocarbon, e.g. alkylene) radicles, such as triazole bis-valeric acid, to polymers having intrinsic viscosities of 0.2 to 0.3, 0.7, 0.9 or higher.  The bifunctional amide-forming reactants may be diamines containing at least one H atom attached to each amino-N atom (e.g. tetra, penta-, hexa-, and deca-methylene diamines), dicarboxylic acids (e.g. glutaric, adipic, pimelic, suberic, azelaic, sebacic, p-phenylenediacetic, and terephthalic acids) or amide-forming derivatives thereof, amino-carboxylic acids (e.g. 6-amino caproic acid or its lactam, 7-amino pentoic acid, or 9-amino-nanoic acid), linear polyamides prepared from these substances, or mixtures thereof.  The molar proportion of amino to carboxyl groups may vary, e.g. from 1 : 2 through 1 : 1 to 2 : 1, or where the terminal groups of the polytriazole have all been hydrolysed to carboxyl groups (e.g. by boiling with hydrochloric acid) a diamine alone may be used. Examples illustrate the reaction in metacresol of on the one hand polyaminotriazoles prepared by condensation of sebacic or adipic dihydrazides alone or with hydrazine hydrate or by hydrolysis of condensed sebacic dihydrazide or triazole bis valeric acid and on the other hand hexamethylene diamine, hexamethylene diammonium adipate, N : N1-diadipyl hexamethylenediamine, and condensates prepared from hexamethylene diammonium adipate and adipic acid; also the reaction without solvent of polytriazoles prepared from adipic or sebacic dihydrazides with a condensate of dimethyladipate and hexamethylene diamine.  The products, which may be soluble in cresol, formic acid, methanol and/or water, may be used in films, filaments, softening agents, and coating compositions.  Specification 613,497 also is referred to.
